When LittleFS.begin() or SDFS.begin() is called after the filesystem is already mounted, don't unmount/remount. When an unmount happens, all old Files become invalid (but the core doesn't know this), so you would end up with random crashes in FS code. Now, check for _mounted, and if so just return immediately from begin(). This mimics the original SPIFFS code. Fixes earlephilhower/ESP8266Audio#407
